While the bone dragon was still some distance away from them, Benjamin glanced at the water elemental spirit in the consciousness space.

After being slapped the tail, the elf was not in a good state, and could only hide in the consciousness space and heal itself by absorbing the water element. However, it is reassuring that it heals very quickly, and it seems to have recovered most of it at this moment.

Once the bone dragon catches up, he can let the water elemental spirit drag it for a while, right?

After being strengthened by inexplicable strength, Benjamin couldn't figure out how powerful the bone dragon had become, and whether the water elemental elf could hold it or not, he could only look forward to it in his heart.

"Actually, if you get rid of these mages, turn on the fastest speed by yourself, and use the healing rain to interfere with the enemy's pursuit, you will basically not be caught up by that bone dragon. The system suddenly said, "And fly with them, it is estimated that you can escape for a maximum of an hour, and the bone dragon will be within thirty meters." ”

“...... Don't think about it, there's no way I'm going to leave them behind and run away on my own. ”

"Then good luck. ”

Throwing down the sentence with a little irony, the system also shut up, leaving only Benjamin who was frowning in the air, and a few nervous mages following him.

Benjamin still casts elemental commands and heals from time to time. Whenever the rain fell on top of the bone dragon's head, it would always slow down for a few seconds, adding hope to their hearts.

However, they began to feel more and more aggrieved by this powerless situation.

“...... Master Leila, what are you holding in your hand?" Suddenly, the male mage turned his head during the flight, looked at Leila, who had been silent, and shouted suspiciously.

Leila looked up, spread her hands, and said, "It's the skull fragments of those lichs." ”

"You're ......"

"There must be some special reason why these undead are able to produce that kind of force field that restrains magic. Leila stared at the dirty piece in her hand and said, "If we can find it, we might be able to change the situation!"

Hearing this, the other mages were stunned.

"You're going to ...... Do you want to start researching while you run away?"

Leila nodded, pulled out a few more glass test tubes from her backpack, and said, "I have participated in the research of the undead group before, and I have learned a little from a few teachers, you can try it." ”

The mages opened their mouths wide and didn't know what to say.

Flying is indeed not such a mind-consuming magic, and with Benjamin with them, they have little effort to control. But materials research ...... Especially for the extremely complex subject of the secret of the dead, this mental drain is great.

In fact, to be able to participate in the undead exploration team, each of them is not only proficient in dark elemental magic, but also knows something about the academy's undead research. They would investigate the habits of the undead, and they would conduct a number of experiments on the unknown energy extracted from the wreckage.

Therefore, Leila's words moved them.

“...... I'm here to help, too. The male mage gritted his teeth and spoke. He retrieved a piece of the Lich's remains from the material chest. He used his magic to carry a potion pot, and as he flew at high speed, he lit a fire in the pot, trying to maintain its balance.

The other mages also forcibly calmed down and entered a state of study. They discussed the composition of the lich remains, took out various experimental potions, put them in the pot with the lich remains, and began to carefully refine them.

It's a somewhat magical picture.

Benjamin flew to the front, interfering with the bone dragon with healing rain wires, and fled for his life. Behind him were Miles, who was lying on a flying plank, and a few mages who were doing research while running for their lives.

Although they seemed to be in a hurry, they soon somehow pulled out a few wooden planks and put them together into a rudimentary laboratory table. They put all kinds of equipment on it, using magic to maintain balance, some are responsible for dispensing potions, some are responsible for experimental operations, and some are responsible for recording data...... The whole process was carried out at the same time as the hasty escape, and the sense of disobedience was strong, but somehow, it was quite decent.

“...... Cow pen. ”

Listening to the discussion that gradually became more intense, Benjamin couldn't help but look at them a few more times, showing a look of admiration.

What kind of monsters has his academy cultivated?

It's just that Benjamin didn't dare to put all his hopes on them. The undead is such an esoteric subject, and there may even be a lot of plane rules involved, and it is difficult for them to study anything in such a few tens of minutes.

He still decided to take matters into his own hands against the bone dragon.

"The simultaneous activation of the Deep Sea Realm and the Arrival of Water should produce some unusual reactions, right?" Thinking of this, Benjamin suddenly asked in his heart.

"Probably. ”

"If I activate both at the same time, plus the Water Elemental Spirit, even if I face the Bone Dragon head-on, I should be able to hold it back for a while, right?"

Hearing this, the system was silent for a few seconds and asked, "Do you want to ...... Run away with them?"

Benjamin nodded, and said in his heart: "There is no doubt that if we split up, there is a good chance that the bone dragon's target will be placed on me." I still have a state of nothingness, and with so many hole cards, self-preservation is definitely not a problem. And as long as they flee towards the ghost abyss and escape from the world of the dead, they should be completely safe. ”

- The Spirit of Bones seems to be very obsessed with the rules, and it is angry that the living step into the realm of the dead, and as the dead, it will definitely not leave the world of the dead.

Therefore, Benjamin felt that the feasibility of this plan was quite high.

"What an amazing, selfless and great feat, I would like to shed a few crocodile tears for you. The system said indifferently, "However, I must remind you that the enemy has gathered the power of the entire undead world, is your phrase 'self-preservation will definitely not be a problem' a bit too floating?"

“...... You don't think I can last ten minutes?"

"That's too much. The system replied without any ups and downs, "Half a minute, it's a little respect I give you for so long." ”

“......”

Benjamin was speechless and glanced at the bone dragon behind him. From the beginning to the present, it has been at least twenty meters closer to them, and it is still shortening, and the pressure on Benjamin's shoulders is also increasing little by little.

If the bone dragon really became as strong as the system said it was now......

Suddenly, he shook his head vigorously and shook the thoughts out. Pressed for time to think about it, he suddenly beckoned to a few mages, interrupting their discussion about what that lich might have been when he died.

"We'd better split up and run away. He said solemnly, "That bone dragon is mainly coming for me, and it shouldn't care about you." You just run away with Miles, don't worry about me, I have my own way to save my life. ”
